인프런 - 라이프타임 커리어 플랫폼

You can learn the basics of blockchain and Web3 while creating your own NFTs.

In this lecture, we will learn how to use ERC20 (Coin), ERC721 (NFT) and create a simple NFT Presale service. We will learn how to use Opensea and Metamask and share development know-how and theory.

This is a Solidity Breakdown - ERC20 lecture where anyone can easily understand Solidity and learn how to connect blockchains and frontends.

If you are planning or operating a WEB3 service but don't know "where accidents happen," you need this lecture. This course does not teach you about coins or development. Instead, it deconstructs the structure of recurring accidents in WEB3 and teaches you how to assess risks based on the boundaries of approval, signature, and authority. After taking this course, you will: ㆍBe able to read the structure of any DApp that comes your way ㆍBe able to assess risks using a checklist ㆍView WEB3 not just as a "technology," but as an "object of design."

Anyone can easily issue NFTs, even without programming knowledge. Anyone can easily issue NFTs, even without drawing.

For those who have only seen Ethereum's structure in fragments, I will organize everything from wallets and transactions to smart contracts and the EVM into a single, cohesive flow. You can follow along even without a technical background.

In this course, you will learn the Solidity language for creating smart contracts.
